Help - Wont Take Formula - Want to Cut Down on BF

[DefNotYummyMummy]

My baby is 6 months and I am going back to work when he will be 9 months (so at least I have some time to play around with). I don't know how it happened, but here we are - he has been EBF since birth. He has never had a bottle. He has started to drink water from a cup, but steadfastly refuses formula from a cup. He will chew the teat of a bottle, and when I tried to put it in his mouth with formula he arched his back and got v. annoyed with me (my DH tried first and got the same reaction).
I am panicking about how much milk he will need when I go back to work. I don't mind carrying on BF, but I am going to be away from him from 8am until 1pm. I was hoping by 9 months he'll settle down and just have milk in the morning and at night. At the moment he has this bad habit of waking for a feed at 7am (which I could do when I go back to work) - but he'll only have a little, and then at around 9am he has a big feed and he falls asleep on the breast for his morning nap. He still wakes in the night and so maybe he isn't hungry at 7am ? Maybe once he takes solids on more regularly he'll settle down and I wont need formula at all ? I'm at a loss really and want to do all that I can to make him happy about the transition.
Any advice would be greatly appreciated as I don't want to stress out even more worrying that he is going to be starving hungry and crying - leaving him with someone else is going to bad enough.
Also - as I am BF on demand - how do I know he is getting enough ? He's growing well and healthy - is that a good enough indicator ?

If you're not going back until he's 9 months, he'll be taking solids by then and will prob need fewer feeds. Chances are that at 9 months, he'll be happy to take formula from his carer. Babies are very clever, and he'll quickly realise you;re not there, therefore no mummy milk bar either. Are you planning on expressing milk to leave for him? He will change a lot over the next few months, developmentally. I'd be tempted not to cross that bridge until you get to it, but somebody else may have more sensible advice.

PS: just realised you'll only be out for 5 hours a day- chances are he'll be fine without feeds between those times by then.

Many thanks for the reassurance duchesse. I just want him to feel secure and happy. I tried expressing and it doesn't seem to work unless they are engorged. I have started solids - but this has been erratic. Today he had nothing, and yesterday he had lots. I have to remember that 3 months is a long time - you are right - he'll be so different by then !

Notso- try hand expressing- I always got much better results by hand. Not wanting to get too technical, but you need to squeeze behind the nipple and areola. If you have trouble working it, call LLL or an NCT breast-feeding counsellor- they will prob come to your house to show you what to do; they always used to way back when my babies were babies.

By 9 months he may be perfectly happy just to have a drink of water mid morning, and wait for you to bring your boobs back.
