My son is 5 months old generally a happy baby, eats and sleeps well on 4 hour easy. In the last couple of weeks he has started crying as soon as he is put down on the play mat or donut ring. He has eaten and burped and is happy but then so unhappy at being put down. He was previously happy playing on the mat for quite a long time so what could have changed? I have a 2 year old too so holding him all the time is not an option and my back isn't strong enough to keep him in the sling plus I want him to be happy with some independent play.
Any ideas?
Thanks x
