I put my DS into daycare three days a week when I went back to work then after 6 months I had to cut back my work days to one day a week due to my health. The centre was fine with that. So now he goes once a week and he really likes it. It did take him about 6 weeks to get used to it though. He gets to do lots of things there, art and craft, play with toys that are different to home, socialise etc. The only problem that we've had is the sickness!! He has had so many colds, gastro, conjunctivitis, hand, foot and mouth...ugh! That part I find really hard but I guess he's building his immune system.
I think you're doing the right thing by giving yourself a bit of time to yourself. That way you won't get resentful and exhausted and the time you spend with your DS will be so much better for the both of you.
