Breastfeeding - not interested and falling off nipple

[DoAndroidsDreamofEwentheSheep]

My baby usually feeds 3-4 times a night but in last few nights has just not been interested it seems. Will feed for few mins then just let go. IA not screaming or seeming hungry so am not sure if is just not needing it anymore? Is 4 months old. (And a 'PFB' so am paranoid about EVERYTHING!!) DH is trying to convince me all is fine as is on 80centile but am worried about being starving!

Teething can make babies less hungry.

Ah thank you! We are definitely going through that- hands constantly being chewed and everything soaked in drool!

Just watch out for the teething poo!

Might be due to teething
Could be that they are feeding faster- my 3-4 month old only fed for 2-3 mins at a time- an improvement from 45 mins each side as a newborn :)
Or they might be getting distracted easily

Check they are getting enough by whether they look hydrated and nappy output

Are you getting enough wet nappies? If so please don't worry. They go through little phases, as pp said teething will do this, or DD was a very infrequent pooer (like once a week). Before a big poo she'd go off her food (normally for about 24 hours) then it would all come out and she would want to feed constantly.
At 4 months she's probably starting to drop feeds as well.
