Hi Lewis' Mum.

I found that my 3rd son went from being a fantastic sleeper to being unsettled at night around the 16 week mark. I do honestly think it was due to him start to get hungry, that being said I still held out til he was about 4 1/2 months and he was given some rice cereal morning and night, slowly increasing to small amounts of vegies and fruit. I maintained this until he was 6 months old and then introduced all the foods to him.

I no I go against the majority of withholding solids untill 6 months but I have read several different reports on the benefits of slowly introducing solids from 4 months, so I wasn't concerned with that. It too another couple of months for his sleep to return to going through the night and now he is just a champ and sleeps through 11 hours at night.

Good luck, you will ride through this phase.
That sounds like us at the moment, but she's getting such bad gas it's effecting her sleep, but if i don't give her food she gets quite agitated, she yells at me, it's stll amusing to me to see a 5.5 month old banging her fists on a high chair wanting food
