Hi Ali,
I think it's right to stay optimistic - She seems to be doing really well from what I've heard - I bet she'll be sitting up soon... she's just taking her time! You'll all be really shocked one day when you leave her laying down for a while and then walk back into the room to find her just sitting there!
Glad Charlotte's enjoying the sunny weather

It all seems a bit much for Anna atm and she's got a nasty heat rash... Otherwise she's doing really well

- started holding her head up on her own this weekend - it's just amazing
Hope you enjoyed your bbq
Pass my best wishes on to Samantha for me, Take care you three x
