My daughter didn’t sleep through until she was almost four, I would maybe just make sure that your child is really warm and comfortable. Also for you to be relaxed that’s probably the best advice I could give. Sometimes there is nothing wrong it’s just the child being awake and it’s as simple as that

I like the 7 to 7 routine outlined in tizzie halls book save our sleep – bub goes to bed at 7 and wakes at 7. She outlines feed times etc and some of the book I didn’t like but this routine worked for us. From memory if breastfeeding it was a feed every 4 hrs through the day but routines vary depending on age. Making sure they are warm enough through the night, well fed through the day and follow the same night routine – bath, boob/bottle, book or straight to bed

In addition to what others have said about food, I find that clothing and blanketing appropriately according to the room temperature, is vital. My daughter has been sleeping through the night (i.e. minimum 8 hours uninterrupted) since she was 4 weeks old (I know, I got very lucky!) but she will wake if she happens to be too hot or too cold in the middle of the night.

Depending on the age of your baby you could give a few spoonfuls of baby cereal with their night feed before you go to bed yourself (perhaps the 10.00 feed) A relative of mine tried that with 2 or her children when they still small enough to be in their bassinets. Both of them slept longer between that feed and the next one than when they weren’t given it.

It depends on the age of your baby. I would suggest a good feed and a lovely warm lavender bath before bed with cuddles. Then into bed. It really depends on the baby but 1 or 2 wakes (max) should be it during the night for a feed and/or nappy change and then straight back to bed. At about 4-5mths for my kids this is what I did.
But remember it may not always work this way. Every one and every baby is different. Some may need to more food etc. My kids love to sleep, even a couple years later they still do. good luck!
