I EBF'd my eldest daughter until she was 11 months and have EBF'd my 4 month old up until now. I really enjoy breastfeeding and never thought I would have to introduce formula this early on so this is a bit hard for me. I have only just started giving her a bottle of formula at bedtime because she has had 2 weeks of waking up every 1.5-2 hours to breastfeed and as I've also got a 3 year old to look after I just can't take it anymore. I am also trying to space out her feeds during the day which is hard but I'm thinking that her frequent feeds during the day might be one of the reasons for her frequent night feeds... I am really worried that giving her formula might cause problems for BF as I definitely don't want to stop it yet...Any advice?
