Sorry just have to share this, saw friends 7 week old today, doing reakky well she is BFing but giving her a bottle of formula at night. Today she said she was having half a rusk in it as well.
Now I know HVs and MWs don't recommend it now but I was still when she said it. I said you aren't supposed to now and she asked why and I said I think theres a risk of choking didn't go into the allergies thing and basically you are grinding up a sugary biscuit into your babies milk.
Think it's another one of these things that people don't believe a baby can survive on just milk for 6 months.
