Our DD2 is 10 days old and is feeding and sleeping really well during the day. She is happy to sleep in her moses basket, car, etc etc but from about 10pm through to 4/5am she won't settle unless she stays asleep in our arms. Due to her jaundice we are feeding her breastmilk and formula and she tends to have more formula in the night because I can't keep up with her demand. We were thinking that she might be having problems digesting the formula at night but can't really think why it would be different to the daytime. Any advice gratefully received.
