Hi Greedygirl,
I like you have been worrying about my now 8 and a half month old daughter going to a nursery for 3 days at the end of September.
She is still breastfed and has solids 3 times a day. She won't take a bottle and was refusing formula from a cup.
Over the bank holiday weekend my husband took her out in the pram and gave her some milk midmorning from a Tommee Tippee cup. She only took a few sips. I have been giving her a cup of water or very dilute apple juice from a Doidy cup ( which has sloped sides and has no lid) after lunch and dinner which she can drink a little from.
Today she managed about 40 mls formula midmorning when I took her out in the pram and seemed to quite like the taste and I also mix in formula to her cereal in the morning.
Saturday I got her down to 3 breast feeds and yesterday and today first thing in morning and before bed. Seems ok so far with little engorgement and milk still present. Just made sure to get her to take from both breasts during a feed.
I also give dairy/cheese/sauces/petit filous during the day when she only has juice and water, so I think she had enough calcium and protein that way.
I think I will try to keep going with 2 breastfeeds a day when I am back at work, but will just have to see.
Plan would be breastfeed, breakfast cereal mixed with formula, formula from a cup midmorning, lunch with water/juice, formula from a cup afternoon, dinner with water/juice, breastfeed before bed
I hope some of this helps and I am sure it is easier to get the childminder to give formula than from you!!!
