I flew with all my kiddies as babies & have never had any probs, either a dummy to suck when landing or feeding them at that time will help the pressure in their ears...

We just got Zy's 8wk immunisations last wk, due to us travelling & me not wanting a reaction whilst o/s.

Maddy was rolling at 9wks both ways front to back & back to front, there was nothing I could do to keep her on her back & she hated being swaddled so I just let her roll all over her cot...
So if bubs can roll then I'd allow them to sleep on their sides? Zyon's too chubby to roll... hee hee

Off to shops today, back to a crapload of school kids b'days coming up & so gotta go get presents... grrrrrr
