DS is 22 wks old and is BF and then topped up with formula each feed. This last week I've been trying to replace a lunchtime feed with just a bottle as I won't be able to juggle solids, bottles and boobs. This was going ok, DH had the week off so he was giving him the bottle. DS kept crying for the boob but DH eventually got it down him. Then on the weekend DS was vomiting and all he would drink was boob. So back to square one! I need to introduce a second bottle this week really. How do I do this without DH's help and without the poor baby crying for my boobs? It breaks my heart!

Please help.
