But for every bad moment there have been a hundred more fantastic ones and I as I was feeling a little nostalgic I thought I'd have a rummage through the photos of us taken over the last few years.
He knows that his baby brother will be arriving soon, but I can't help but wonder what he will make of the new situation. I know in time he will be unlikely to remember the time when he had his Mummy all to himself and I also know he will be a great big brother. As I grew up an only child I can't really imagine what its like to suddenly have a sibling join the family, Aaron is one of three but he is the youngest so never dealt with a new arrival.
Over the last couple of days Leo has been increasingly 'lovey', I'm not sure if this is just to do with school (he's never been that happy about going, and since his week off while it was closed he's been even more upset about it) or if he knows things are about to change. He's been very cuddly and has spent a lot of time saying 'I just want to be with you' and sitting cuddled up to me on the sofa.
In less than a week he will no longer be my baby ( not that I've thought of him as one for a long time - it actually really bugs me when people refer to kids as 'the baby') and he will definitely be my 'big boy'
