Oliver was 4 weeks old yesterday. We changed him onto cow and gate newborn milk today, hoping it will help with his gripey tummy. He has 4oz of milk every 4 hours. He sleeps really well at night. Last night we fed him at 11, he woke at 2.40am and then at 6.45am. He goes straight back to sleep after his night time feeds, very pleased with how he's doing.
