Access when baby is at childcare

Hi
Interested in what other single mums have done regarding access when they are back at work at their baby is in childcare?

My 7 month old girl will be breast-fed (and assume on solids) at that stage (the centre is 10 mins down the road luckily) and in care 3 days a week.

I am not going back full time as I want to spend time with my girl (but cannot afford to stay at home full time).

Its not amicable between me and my ex partner; he left when I was 25 weeks pregnant. Currently he sees my girl 4 times a week.

What have others done?
