16 week old drinking less

[mummyof32022]

So, my DD is 16 weeks old. We had her second lot of immunisations last Wednesday, so 5 days ago. I'm not sure if it's related but since then, her feeds have dropped significantly. Before them, she was drinking 5/6oz every 2-3 hours. Now I'm lucky if she drinks 3/4oz every 3-4 hours. She's fine in herself, she's still having wet and pooey nappies etc. what could it be? Or am I just worrying for nothing. We were at the docs today as she had conjunctivitis yday (suddenly disappeared overnight 😂) and he didn't seem concerned when I mentioned my worries

My LO is a little older (21 weeks) but has never taken more than 6oz, I can get 5oz in him but most of the time he takes 3-4 then I give him the rest after 20mins or so.

I've no idea why! He's never been the best feeder but is the perfect size for his age, sleeps ok, happy, normal nappies etc.

I just make sure I feed him more often to make sure he gets enough in the day but that's usually only around the 25oz mark which is supposedly the minimum for his age... some days we don't reach 25 though. I did begin to introduce small amounts of food at the 4 month mark for some extra calories - whether this is right or wrong I don't know! But he has taken to it ok.
