Feeding routine gone to custard

For the last... oh, more than two weeks now I think, Alex has been wanting to feed every 1.5 hours during the day I can usually stretch it out to 2 hours but he gets pretty grumpy about it. At night he'll do 4-5 hours.

It used to be that he'd easily do 3 hourly during the day and 6-8 hours at night.

What's gone wrong? Surely no growth spurt can last this long?

How is your supply? Perhaps you could try a supplement or maternity tea to makesure he is getting a full tummy at each feed?

it may be a growth spurt. you may have, as sterryn said, to "go with the flow".

Ella also does a similar thing. She started off feeding every 3-4 hours and now feeds roughly every 2 hours during the day (at night she sleeps anywhere between 8-11 hrs, so I don't mind feeding her so much during the day). At first I was worried that it was too much, but she gets a decent amount at each feed and is having good weight gains and is a happy baby so I am not too worried now. Good to know that other babies are doing a similar thing.
Is he taking in a good amount each feed? Have you had him weighted recently?
