DS is 6wks and has recently started to lengthen his feed times from around 10 mins up to around 15-20. Just wondered what is normal? Also, he is going around 3 hours inbetween feeds most of the time, but in the early eve and again in early morning it can be as short as 1 1/2 hours between feeds. When will it get longer during the night too as feeding every 3 hours is killing me!
