Ok, currently 7lb 12oz 4 week old (tomorrow) DS. Mix feeding. He's feeding every 2 hours, about 90ml, sometimes every hour and a half. I'm getting no sleep and struggling. Can't just stay at home and sleep when he does as have a variety of appointments for him that always seem to start around 10am, then other commitments that I can't pass on to anyone else and can't leave. So we're usually out of the house for an hour and a bit in the morning, then 3-4 hours in the afternoon. I'm shattered and struggling to stay awake tbh. On the formula box it suggests that formula babies go 4hrs+ between feeds. 2 lots of that in a night would be amazing. So how do I get that?
