I wouldn't drop a bottle - he still needs his milk at this age.

Sleeps - usually around 9 months (I said usually!!) they will drop to 2 sleeps a day ...

Zander sometimes does 2, sometimes does 3 - depends how long he has slept for if that makes sense. Like yesterday he did 2.5 in the morning for a CHANGE 9.20 - 11.45sm - and then did 50 mins later in afternoon, 2.30 - 3.40pm so I didnt put him back down until bedtime at 7ish.

Do you put him down at certain times every day or depending on what time he gets up, when he starts to seem tired etc? Stretch him out for 15 mins the first time, see how it goes ... if it doesnt work he may have got overtired - play around with it and see how it goes.

But yeah dropping a sleep around this age is "normal" - but keep up with the milk. When you say he didnt want his first feed until 10am - what about when he got up out of bed in the morning - did he still have one then?
