How much expressed breast milk would a 10-12 month old take in one feed?

I've been exclusively breastfeeding my son and haven't used a bottle yet so am looking into getting them. For a 10-12 month old baby, what bottle size is standard for one feed provided that the majority of his daily calorie intake comes from the breastmilk while he may eat some of the solids offered at the dining table?

My breastfed DD took 120-140ml of expressed milk when it was needed at 10-12m.

If baby has never had a bottle though, no guarantee at all that they'll actually drink anything, so I'd try very little like 20-30ml and top up if it goes well. If your son doesn't take it by bottle, you could try a straw or sippy cup.

If you mean formula, that is likely to be more. DS who was formula fed by that age took about 150ml then, I think.

My baby never took more than 2-3 US oz at that age. But I breastfed him at night, morning and evening and was on 3 meals a day by 9 months so milk in the day was more like a snack.

Thank you for the reply, so no need for a big/long bottle of 200+ ml for expressed milk then - as I've been shopping for bottles and wanted to establish what size we need. We tried a feeding cup in early days but never any bottles until recently he held it and put the nipple in the mouth but didn't drink from it, so it might just need more getting used to.

Thanks, I'm planning to still breastfeed the rest of the day and only use bottles when I can't be with him for work etc, so probably a small size bottle will do!

My daughter switched to formula at 10 months and had 5oz bottles of formula except before bed when she had 7-8 Oz.
This mimicked her breastfeeds as she had shorter day time feeds then a longer feed before bed

At that age they don’t really need any milk from a bottle presuming they’re eating meals and drinking water. 10 month olds should still have milk but breastfeeding before/after work will be fine. 12 month olds aren’t supposed to have bottles at all because they’re bad for teeth and they can get what they need from cows milk in a cup, breastfeeding when you are around, even 2 portions of food containing dairy e.g. cheese or yoghurt is sufficient. So I wouldn’t bother at all with the bottles or pumping because it’s an unnecessary faff. Also we tried sending in bottles to nursery when DS started at 9 months and he just refused there. He’d have them morning and evening at home but when he saw the older babies having their snacks he wanted that instead so we gave up!

I wouldn't bother trying to get DC to take milk from a bottle at 10-12 months, especially if there's been little interest so far. Just use a cup.

OtterMummy2024 · 20/06/2025 12:25

You might find a cup works by then, I use the 360 Munchkin cups as easier to clean milk out of then some types.

Eastermuppet · 20/06/2025 12:28

I breastfeed for over 3 years. I went back to work fulltime at 9 months, he never took any expressed milk ! Fed frequently when I was with him, just food and water while in childcare. I wouldn't worry too much

My daughter refused bottles from nursery staff at 12m but happily took from her dad or granny. You might find baby doesn't actually ask for any milk when you're not there, but I definitely think you should prepare the caregiver to be ready to give it if baby is unsettled and won't soothe with cuddles, food, toys.

No need for bottles. Just use a drinking cup for drinks. Having too much milk at that age can suppress the appetite.

mondaytosunday · 20/06/2025 20:29

Agree no bottles. You’d be stopping them at a year anyway. My DD refused them so used a sippy cup from about six months.She self weaned at 12 months.

IAmTooOldFor · 20/06/2025 21:19

My 5.5 month old takes 270-300ml breast milk first thing in the morning and 150-200ml for each daytime feed, 200ml+ at bedtime. We’ve recently started her on food so her midday milk feed has reduced. I would buy the big bottle!!

I don’t recommend introducing any bottles, most calories at this age are from proper meals.

At this age I breastfed when I was at home, it’s more comfort than nutritional after 6m.

Have you tried the doing cups? Much better for transitioning to a cup than a spout.
