How long can I leave DD to play?

[WhoahThere]

DD is 6.5mo and can now sit up, which she's thoroughly enjoying. She'll sit for 45 mins on a soft mat in the kitchen eating playing with toys while I potter, wash up, etc - whilst chatting to her of course. Is it ok to have her sitting and playing for as long as she's happy to? Or should I be doing more with her?

And does she still need tummy time? It's tempting not to bother now as she finds it frustrating and isn't spending any time lying on her back these days so shouldn't be at risk of getting a flat head....

i'd let her be. she's having fun playing, she has you for further entertainment - sounds great. I'm sure she'd protest loudly if she wasn't happy. If she's sitting steadily then she's working all the muscles she'd use in tummy time.

9mo dd2 still screams if put down.

Sorry Flora!

Yes, let her stay there as long as she is happy. Babies need to learn how to occupy themselves.
I would continue with tummy time to develop stronger arm and shoulder muscles.

That sounds great - she is having a lovely time playing with her toys, secure in the knowledge that you are around if she needs you :)

Tummy time - never really did it with either of mine and neither of them appear to have flat heads or have suffered any developmental delay...

Just enjoy it while it lasts! It was the easiest stage with DD and I miss it- now she hangs off my leg whinging to be picked up!

Agree with Flora.
