Ask any UK mum what wrecked her first year the most and “sleep” comes up before anything else does. Not the cute kind of tired: the kind where you’re googling “is it normal for a 7 month old to wake 10 times a night” at 3am with one eye open. If that’s you right now, you’re not doing anything wrong. Baby sleep is genuinely hard, it’s rarely linear, and most of what you’ve read online oversimplifies it.
Why baby sleep feels impossible right now
Newborns don’t have a day-night body clock yet, and it takes several months for melatonin production to settle into anything predictable. Layer on growth spurts, teething, developmental leaps, separation anxiety around 8 to 10 months, and normal illness, and you get a pattern that looks chaotic even when nothing is wrong. Mumsnet’s sleep forum is full of exhausted parents comparing notes on exactly this: a baby who slept beautifully at 4 months and then fell apart at 6. That back-and-forth is the norm, not the exception.
The sleep training debate: what UK mums actually argue about
This is the topic that splits parenting forums down the middle, and it’s worth laying out both sides honestly rather than pretending there’s one right answer.
Parents who use graduated methods (sometimes called controlled crying or controlled comforting) say the short-term discomfort is worth it: within a few nights to a couple of weeks, many report their baby falling asleep independently and night wakings dropping sharply.
Parents who take a no-tears or attachment-led approach argue that responding to every cry builds trust and that babies can’t self-soothe in the way sleep-training language implies, especially before object permanence develops around 6 to 8 months. They often favour gentle-settling methods and simply accept broken sleep as a temporary season.
The honest answer most experienced UK health visitors give is that both approaches are safe when done thoughtfully, and the right one depends on your baby’s temperament and what you can sustain. Six months is often cited as a sensible earliest point to consider structured sleep training, but plenty of families wait far longer, and that’s a valid choice too.
Sleep regressions by age: what’s normal
| Age | What’s usually happening | Typical length |
|---|---|---|
| 3 to 4 months | Sleep cycles mature, more waking between cycles | 2 to 6 weeks |
| 8 to 10 months | Separation anxiety, crawling practised in the cot | 2 to 4 weeks |
| 12 months | Walking, one nap transition looming | 2 to 3 weeks |
| 18 months | Language explosion, nap resistance | 3 to 6 weeks |
| 2 years | Nightmares begin, cot-to-bed transition | Variable |
If a regression is dragging on far longer than these windows, it’s often not a “regression” anymore but a habit that’s formed around it: worth addressing directly rather than waiting it out.
Co-sleeping and bed-sharing: the safety facts first
This is one area where it matters far more to get accurate, current guidance than to repeat forum folklore. The Lullaby Trust’s safer sleep advice, which UK health visitors follow, comes down to a few consistent points:
- Always place your baby on their back to sleep, every sleep, day and night
- Room-share with your baby for at least the first 6 months, for every sleep
- Keep the cot completely clear: no pillows, bumpers, toys or loose blankets
- Keep the room between 16 to 20°C and avoid overheating
- Never sleep with your baby on a sofa or armchair
- Keep the sleep space smoke-free
On bed-sharing specifically: many UK parents do it, whether by choice or unplanned in the middle of the night, and the Lullaby Trust’s position has shifted from blanket discouragement to harm reduction: keep adult bedding away from baby, remove headboards with gaps, never bring pets or other children into the bed, and avoid it entirely if you or your partner have been drinking alcohol or taking anything that causes drowsiness.
Night weaning: when UK mums actually do it
There’s no single “right” age, but a common pattern is to wait until solids are well established and weight gain is on track, then drop one night feed at a time roughly a week apart, offering comfort instead of milk.
When it’s more than normal tiredness
Most sleep struggles are developmentally normal, but speak to your GP or health visitor if you notice:
- Loud snoring, gasping, or pauses in breathing during sleep
- Sleep problems alongside poor weight gain or feeding difficulties
- A sudden, unexplained change with no obvious developmental trigger
- Your own mental health suffering badly
What real UK mums say actually helped
A few themes come up again and again: a boring, predictable bedtime routine matters more than any specific method; white noise left on all night helps many babies resettle between cycles; and the biggest single improvement often comes from adjusting nap timing so the child isn’t going to bed overtired.
Quick answers
When should a baby sleep through the night? Many babies are capable of a 6 to 8 hour stretch by 4 to 6 months if feeding and weight gain are on track, though plenty of healthy babies wake well beyond that.
Is it too late to sleep train an older baby or toddler? No: gentle, consistent changes work at any age.
Should I keep a dream feed? Trial it for a week and drop it if it isn’t earning its place.
