i am wondering if this is actually sleep regression, just the natural order of things, or if he might need more milk during the day.
DS is 5 months old, and has been sleeping 7-8 hours straight through the night since he was about 3 months old.
This week, it is taking us slightly longer to get him to bed for his night sleep, even after his night time feed, and he has woken up at 3-4am every single morning for a feed. In the past, if he did wake up, which wasn't often, I would cuddle him for a minute, then put him down and he would go back to sleep. When he wakes up now, I try that a couple of times, he relaxes for a minute then starts crying until i pick him up again. Once he's had a bottle, he then goes back to sleep.
His day time naps are still ok, except he has taken a liking to sleeping on our couch instead of his cot bed (he's now too big for his moses basket).
He is a big baby (verging on 91st percentile), and weighs around 9kg. The formula we have doesn't have an appropriate guide for his weight and age (it stops at 7.6kg for 5-6 months), so I have been going by NHS guidelines for formula (150 - 200 ml for each kg). This means he should have 1,350 ml - 1,800 ml per day. He usually has 5-6 bottles of 240 ml per day. I try to feed him every 3 hours, but sometimes he refuses a bottle, so it seems that he is getting enough.
At the moment, we don't have a napping and feeding schedule, I kind of just roll with it and look for his feeding and sleeping cues.
He is also teething at the moment, so could this be related?
Sorry if this is quite long!
