Hi! Just looking for some advice on my 8 week old. The last week he has really struggled feeding (arched back, crying, appears to be in pain). He also makes a lot of mess during feeding and had to be changed every time as milk soaks through the bib and babygrows. I was using tommee tippee bottles but thought I'd try him on a MAM bottle which we received free. He seem to feed much better on these. No mess either! This was a newborn bottle with teat 0. I ordered some larger MAM bottles and they come with teat 2. He seems to be struggling again and making a mess. Should I stick with the newborn teats or try size 1 teat? Just conscious for his age he should be on size 2 but he just seems to gulp it to quickly and make a mess. Size 0 seems to slow him down.. First time confused mum here so grateful for any advice!!
