Has anyones LO ever acted not interested in eating? Even tho it's been 3 hours?

Liam is 13 weeks. bottle and formula fed.

He ate last night (4oz) at 10:00pm before bed.

He woke to eat at 5:30am. And only took 2.5oz But that isnt too abnormal for him .went back to sleep as usual and slept til 8:30 when he wakes.

Ate around 8:50am and only took another 2oz.

Then, he takes a short nap at 11 today and will often take a bigger (or full feed at least) before that nap.

Not today! He took a whole 2.0 oz!!!

And now he's in his jumper playing and talking and smiling and jumpin along.

I feel Like I should keep offering a feed !! Or should I wait for him to ask for it?

Idk if this is a phase, or leap, or whatever, but ... This child has got to be hungry! You would think!

We do baby led and scheduled feedings. If he wants to eat we feed. But if it's going past 3.5hours in the day time, like if he's napping, then I'll offer a feed and 99% of the time he takes it.

He has an Appt to discuss this bc Im worried about it but wanted to see if anyone else has went thru the same thing. Thanks a bunch.
