DD (now 23 wks) is suffering from second-child syndrome I.e she spends a fair bit of time in bouncy chair, or on her back on activity mat whilst I try and prevent 2yr old DS from killing himself. She is not rolling over yet and I was thinking this morning she doesn't really have any tummy time at all.
She is a happy, contented baby and her head shape is fine. Am I harming her by not doing tummy time? She really objects if I do try it - about 30 secs is about her maximum threshold.
