Back to work, bottles for EBF baby

[887PooleFan]

Going back to work, baby is EBF (7months). I will pump at work and plan is to still breastfeed evening and morning and weekends. I'm worried about bottle preference. Currently looking at Philips Avent or MAM. He likes the Avent as an odd bottle but I'm worried this isn't similar enough to breastfeeding and if I switch to this, he won't want the breast anymore.

Also, any recommendations on how much milk to leave for the nanny? Do I make up lots of 5 oz bottles and see how much baby eats?

We live abroad, I have no option but to go back to work (we only have a 6 months mat leave technically, I added some holiday to cover me to 7 months).

When a baby is this old i don't think you have to worry too much about bottle preference. Breastfeeding is very well established at this point and they are usually pretty efficient so not wanting the faster flow of a bottle.

There’s a good guide here in how much milk they will need
