DD has had a great routine of feeding (6am, 10am, 2pm, 6pm and 10pm) and sleeping for the last month but in the last couple of weeks its all gone crazy. She's 16 weeks old so I think a lot of things are happening at once - she seems to be teething, seems to be hungry so perhaps I need to give her solids or back to 6 feeds and she is tired in the early evening so probably need to bring bedtime forward. If I bring the feeds closer together with the last one being at 8pm, will that keep her full until 6am? Should I start weaning or is it too eatly? We're having a lot of 4am wakes and with a 6 yr old to get to school in the morning it's starting to take its toll! Any advice? Thanks
