buying stuff for baby


So I'm nearly 20weeks, My oldest boy is only 11 months old, But with him by 20weeks he had a nursery set up, Had all his clothes and extra bits, I was even thinking about doing the hospital bags but with this one I haven't bought 1 single thing for him, I mean he doesn't need much bigger items as I still have them from my 1st born, but I just can't seem to find energy to start shopping for him, Might be due to not having enough time with running round after my oldest or when I get paid my money just goes on my oldest, and with his birthday round corner as well, I just like to always be ready and have everything set up but fill sorta out of it this time round, How far was you when you had everything sorted for your baby,
