My dd is almost 5 months old and is exclusively breastfed. I feed on demand and she always has several wet nappies per day. However, she only poos once a week. She's only gained 200g in weight in the last 6 weeks as well so for these two reasons my hv recommended switching her to formula. I don't really want to - I want to bf until 6 months at least, and quite possibly longer. It's really easy these days so I'm reluctant to introduce a different method at this stage, but obviously will do it if it's best for dd. I just don't know what to do.
For full disclosure, I'm also taking Sertraline for pnd which is another reason the hv suggested stopping bf. I don't mind the feeding though and from what I've read I think Sertraline is definitely safe for breastfeeding.
Does anyone have any advice? Have you switched to formula for slow growth/pnd/constipation?
