My first post! Hi everyone. We've decided to supplement with formula after dd (18 wks) was not gaining weight. We thought we'd start with one formula feed a day, and keep bf for the rest of the feeds. So... she took the bottle no problem, downed 7oz in about 10 mins - then threw up hugely in 4 instalments. Looked like most of the bottle! Feeling a bit stressed about the whole weight/supplementing thing anyway so I have some questions: was it just too much? Did she drink it too fast; should we switch to a slower teat? She doesn't normally vomit at all. Any suggestions welcome :)
