my 12 wk old DS is exclusively breastfed but since he was 2 weeks old we have been giving him one EBM feed in a bottle at night. DH does this so as not to confuse DS and at night he takes the bottle fine however we have also given him the odd EBM bottle when we've been out and recently he's started to not feed when we've done that -in fact the last 3 times we've given him a bottle whilst out he's kept spitting out the teat and only ended up drinking an oz or so -today i ended up bfeeding him because i couldn't leave him without food but I'm worried because when i go back to work he'll be bottlefed and also if we ever need to leave him with anyone I need to know he won't starve -he's still happily taking the bottle at night so we cant figure out what's wrong -any thoughts/advice/similar experiences?
