DD is 3.3, finally came off meds about 4m ago (still has reflux but usually swallows it back down, only sick once or twice a week now).
It was absolutely horrendous as a baby, upwards of 200 vomits a day. There was no way she could do tummy time, she would be sick and collapse face down in her own vomit, which she'd then inhale.
She was rolling at around 5-6 weeks, sitting upright by herself by 5m (guess she'd had a lot of practice at being upright!), crawling around 9m, I think, cruising around 10-11m. 'First steps' were around then but we were never sure if they were gravity-assisted... First proper walking was on her first birthday in front of both parents and GPs. She's always been an attention-seeker.
She loves football, scooting, swimming, etc. Today she's walked 3 miles. No physical development issues due to reflux whatsoever. (She also had a year's physio for torticollis, often linked with reflux, and again no lasting consequences).
DS is 8m, also reflux, also couldn't/didn't do tummy time. He was sitting at 4m, pulling himself up to standing before 6m, he's been both cruising and crawling for a month or so now and can stand up by himself from sitting and stay standing for a few seconds.
I don't think we have future Olympic champions in the making, I just think that having reflux is a pretty powerful incentive to get yourself upright as soon as possible. Tummy time is vastly overrated in these circumstances.
I second (third? fourth?) the sling/carrier. Get yourself a machine washable one and preferably one that dries quickly. I have several
. The Connecta's my favourite for ease of use and speed of drying. Buckles are the way forward when the baby vomits inside the carrier. Trying to extricate DD from 8ft of material when she was choking on her own puke is not a good memory (though stretchy wraps can also double up as enormous muslins when necessary).
Bumbos are useful too, helping them to sit upright before they can do it themselves. Try propping up the head end of the cot. We use bed blocks www.babyreflux.co.uk/products/Baby-Bed-Blocks.html for both DC. Wedges are pretty useless with babies, they just slide down them or worse, end up upside down.
Good luck. It does get better. DD now cleans up after herself and her brother
