Our DS is almost 20 weeks. He's a great wee BFer and has been sleeping reasonably well. Over the past few weeks (since he hit that 16 week mark) he's gone from having 1 night feed to 2, 3, sometimes 4. I'm knackered and not much fun for our 5 year old daughter. I'm thinking about introducing a bottle of formula before bed. Anyone have any experience of this working? I fed my wee girl for nearly 3 years but things were different for us then. I didn't work for almost the whole of her 1st year. This time I'm going back to teaching when DS is 6 months. I want to keep feeding but I want to be able to function through the day too. What to do?
