My 4 month old has recently stopped sleeping through the night. He wakes every 3 hours now wanting a feed. ( i had him sleeping 8 hours straight from 2 months). He has been breast fed exclusively from day 1. He has also stopped self-settling during the day when he is due for a nap (cries and cries and cries until i pick him up) and will only go to sleep if he has fallen asleep at the breast after a feed.

Im wondering if he needs something more? I was thinking of introducing a formula bottle last thing at night to bulk up the breastfeeding? Has anyone had this problem and tried a formula bottle? Im reluctant to start solids until he is 6 months.
