hi i have a 5 month old son jakson who is breastfed. he feeds every 3.5-4hrs during the day. he has 2 2hr naps and 1 catnap during the day. after his evening catnap around 5pm he wants to feed every 2 hrs. i was told this was to get his calories in so he can sleep all night. i thought he would have grown out of it by now. is this normal to still cluster feed at 5 months? i have tried giving him a bottle as a top up thinking he was hungry but he still wanted me 2hrs later. any tips??
