When can baby sit up with support?

[Clueless79]

Just wondering when it's commonly thought 'safe' to allow babies to sit up - with support. I'm thinking either in a bumbo or supported high chair or even on our knees.

15wo ds loves to be upright especially on our knees to look around. His head is pretty much steady and back seems quite sturdy and strong.

We've also tried sitting him in his bumbo which he liked and are thinking of ordering a high chair we've seen which says suitable from 4 months. My mum, however, has highlighted that this may be a bad idea for the development of his spine - is this right?

Have you never sat him on your knee? I did that as soon as ds could hold his head up. Think we used the bumbo from about 4 months, but didn't get a highchair until he sat unsupported.

I wouldn't put him in a highchair... have you looked into baby nests? There are lots of different supports for babies afaik it is fine for them to use these things as soon as they can hole their head up

A highchair won't be any good - DS used to slide to the side until he could sit unaided. Bumbo wasn't much good as he didn't like it for top long either! It won't be long before he's sitting unaided so don't waste money on a bumbo (speaks from experience) - just give plenty of tummy time to built core muscles and sit him on your knee and he'll get there!

Yeah - all the time - he loves it! Now worrying that we've done him some harm! He loves anything where he can wriggle around and see everything that's going on.

The high chair we've been looking at is this one www.google.co.uk/products/catalog?hl=en&expIds=17259,28095&xhr=t&q=graco+contempo&cp=4&bav=on.2,or.r_gc.r_pw.&wrapid=tlif131360419018510&um=1&ie=UTF-8&tbm=shop&cid=15329915392913443300&sa=X&ei=ZAJMTtyBOYPMhAfKuISQCA&sqi=2&ved=0CFYQ8gIwAA#
and it says it's suitable from 4 months. Can't really see much difference between this and a car seat and I'm not thinking massive amounts of time but obviously wouldn't want to do any harm to his spine developing.

Just realised I cross posted - was responding to RitaMorgan!

Haven't managed to open the link on phone. Will have a look on computer shortly, thanks. At this stage I'm not thinking about feeding just think he'll be happier at our level and also able to learn lots by joining us at the table and generally watching me busy around in the kitchen. He hates his bouncy chair on the floor!

we had a reclining highchair for dd1 and ds which we used from about 4 months when they could hold their haed up and they're both fine. They were only in it when we were eating as they used to get grumpy when they were in a bouncer or on a play mat at meal times. The highchair was a life saver as it allowed them to see what we were doing. We always had it reclined as far back as it would go until they could sit unaided though.

Just make sure you don't actually feed them in a reclining postion though!

Ds is ebf so image of me trying to feed him in a reclined highchair has given me a giggle!

I was thinking more of food than milk

Have had a look at that high chair, Stranded, and it seems very similar to the one I was thinking of. Also the reclining position makes it v similar to swing seat we have which is fine.

So no-one has any knowledge of supported sitting being a problem from 4 months?
