I'm a CM and I would not under any circumstances put a baby to sleep in a buggy, different if they were out and she had fallen asleep, but not put down in one, in fact my last inspector asked if I did as it is not good for them.
And the fact that she was not dressed and you had to leave the baby in buggy on drop off is awful, babies are handed actually to me in this house and yes I start at 7.00 and yes I am always dressed.
We do lots with babies, today we went swimming taking a 4 year old (tomorrow as we have been reminded all day ) and a 14 month old who doesn't walk, but is so confidant in the water cos we have been going every week since she was tiny, four year old can swim she has been going every week since she came to me at 13 months,
Yes 4 month old is young, but I use door bouncers, a leap frog playstation, and a baby ring for that age group.
At the moment have only got the two little ones and 2 after schools as two left this week, but two new ones are starting in July, one only 7 months, interaction goes on all day with them.
