My 7 month old has been weaning since 5 and a half months and has 3 good sized meals a day plus 2*7oz bottles and then 8oz before bed but he has started waking up every 3 hours again (he has never been great but used to go 5hrs for his first stretch) and is really upset. We try to settle him but this can go on for a couple of hours. If we give in and feed him he goes to sleep for another 3-4 hrs. Any tips. Really struggling having not had a proper nights sleep in over 7 months.
