Ive been bf ds2 for 16 weeks. Once a week, dh will give him ebm from a bottle to give me a wee break and to enjoy a guilt free glass of wine! However, my store of ebm has ran out as i just can't seem to express any more than he requires. To be honest I don't really want to start expressing again and building up my supply and was wondering if its okay to introduce a bottle of formula? I've heard this will upset the 'good bacteria' in his gut and cancel out all the good work of bf - and tbh I'm feeling a bit guilty for even thinking about it. I only really want to to do this once a week. Whats your thoughts? I also feel guilty as I bf ds1 for 12months! I did ask my hv but she made me feel like an alcoholic cos I told her I wanted a drink!!
