Baby not drinking enough milk

Hey! I would try and up the size of the teat! I’m guessing your baby is 4-5 months? Try and up the teat for the bottle and baby may take to it, when they start having smaller feeds and not finishing bottles it sometimes means they are getting bored or tired of sucking too hard. Especially if he is still on a newborn teat

We tried loads of bottles as my LG had the same issue, we got the avent Phillips glass bottles, they come with anti colic teats. However we had to buy some teats separate as the flow was too slow and she got frustrated. We are now on teat 4 and she is doing fine, my LG is 7 months old x

Up the size to 2

If he’s able to use a straw, I would maybe try to offer a sippy cup! My daughter because super disinterested in the bottle at about 7-8 months and so we switched her over to sippy cups and now we never really have a problem with her finishing it! You could also try sizing up the nipple on your bottle. If he doesn’t take a straw yet, I recommend offering those veggie and fruit pouches to teach him how because the top of them is straw shaped and they have to suck like they would a straw to get it out. I just would gently squeeze it to let my daughter know “hey look there’s yummy food in here” and after a few tries she finally got the hang of it
