Help! DS is huge and has outgrown his bouncy chair (and wants to sit more upright.) everyone in my breastfeeding group said get a bumbo, it's what everyone uses. So I tracked down a 2nd hand one, went round the ladies house, sat him on it and he looked like giant sat on a toadstool! So no way. He isn't sitting up unaided yet, so what do I do?! Just always have him laid down?
