I realise it's tempting, but guidelines say around 6 months because that is when most babies are ready and because having reviewed hundreds of studies, the WHO agree this is the best age.
Maybe giving solids now won't do any harm, but what if when your baby is older you realise it may have done or has done? On the other hand, waiting definitely won't do any harm.
I've yet to see a baby of 4 months showing all the signs tbh, no Tongue thrust, can easily bring objects from hand to mouth and sit unaided.
Its not so much that it is tempting its more just my instincts telling me she is ready, i I'm not weaning her just yet, i am going to wait a while longer, i only wanted to see how she would react to having a little spoonful and if she likes it then gradually give her more. She always watches me eat, she can take her dummy in and out of her mouth by herself, she sat up unaided for 5 seconds yesterday i was so proud! and she always copies us when we eat, putting her hands in her mouth and chomping so i thought today i would let her try a spoonful and she liked it, there was no fuss
Your right that waiting will do no harm but every mother is different and every baby is different so i guess it just depends,
also before new research the age for weaning was 4 months and it has done no harm to us.
Like i say, everyone is different!
I'd argue that allergy rates, digestive issues and other complaints are at an all time high. You can't conclusively prove that early weaning caused it all, but it's suspicious IMO.
We did an NCT weaning course - the signs of a baby being ready for solids are:
Sitting with little to no support
Bringing things quickly and accurately to the mouth
Loss of tongue thrust reflex
If you want to see if she's ready, give strips of banana while you eat. When she picks them up and has a go at eating them, she's ready. Simple!
We did that with our LO, and we started BLW at 23 weeks.
