My girl is 5months plus, and lately she seems to be having a growth spur. she was able to sleep for 5-6hrs through the night previously but she wakes up every 2+hrs in hunger crying for milk. PD has given us green light to start solid as she is constantly going hungry, but it is impossible to give her solid in the night and she wouldn't drink more than 100ml each time. Anyone with similar experience can advice?
