2½+1+1=??

First there was 1½, then I entered the family, then came Quinten and now Lily. We're 4½ people in this family, in a 2 bedroom apartment and making it work is exciting - not always good exciting but never the less. When Kate turns 4 this November we've lived here 2/3 of the time on the lease and we cannot wait to get out of here, as much as I love Mortsel I hate the traffic and I hate the neighbours, Steve probably hates the traffic more than me but then again, he gets stuck in it every single day he has to go to work - poor guy!
We have Kate every second weekend and to be honest, I don't always think it's enough, Quinten loves his sister and she loves being here, not sure she always loves him but that's children right?
I love all my children and I consider Kate mine as well - to a certain extend. I enjoy that sometimes I can 'hand over' the responsibility of her to her father and throw my hands in the air with a "Fine! Be that way!" Simply cannot do that with neither of the other two, I am the problem-solver when it comes to them and the safety net.
We are, at best, harmonic and at worst.... don't get me started. Steve and I do not agree on the rules, he says I'm too strict and I say he's too soft. Maybe because I expect so much from Kate, because I do not know what she can and cannot and so little of Quinten because I know exactly what he can and can't. Steve sees Quinten as a mini Kate and gets frustrated when he does not understand or does as told, he sees Kate as his little girl and I think that it often scares him when she grows up and develops as quickly as she does. Not having her on a daily basis is frustrating for him I believe, he misses out on so much and being a man, his eye is not for the details but for the whole picture. I see the details, I see every little thing. I think it's because I'm a mother :P A mother of 2½
