I find routine is key, even at these early stages. He is breastfed, and will always try to feed to sleep. I will wait until I can see he is getting drowsy and start to remove the breast. Sometimes he will wake straight up and want to continue feeding which is fine, others he’s too far past it and will snuggle in. I won’t let him use me to comfort suckle (first thing I done with my daughter and regretted it come 1 year old and she was still there comfort sucking every night!)
My son will fall asleep no problem during the day in the car seat or the pram - for that I feel extremely lucky! But much like others as soon as the motion stops 8/10 he will wake. If there’s things to be done he is popped in the carrier and we power on 👏🏼
For naps in the house as soon as I catch his sleepy cues I will put him into his star blanket. I’ve made that an association with his day naps and believe this is how he will settle to sleep and be put down during the day.
Nights are a little different. It can be gruelling on an evening to lift and put down baby 4-6 times in a 2 hour time space but I’m not one to leave a 3 month old inconsolable and also not going to give in to letting him sleep on me (another thing I done with my daughter that I wouldn’t do again) I do the same thing over and over until he is settled. It has decreased a lot with this routine in the number of times I need to do this each evening so I assume it’s working 🤷🏼♀️
Feed - cuddle and rock to sleep - hold for 10-20 mins and put down. White noise is a must for us, and keeping the hand on his chest for a good minute once he is down so he feels the pressure and not just suddenly that he is away from me. If he doesn’t stay sleeping I won’t pick up as soon as he starts to make his whingey noises, I’ll keep the pressure on and pat his bum for a good minute or two to see if he is going to escalate it into a cry.
As I say I am far from an expert! Hopefully people with more knowledge will comment in the morning and give advice, but these are the things that work for us.
My current issue is my son will go down for between 4-6 hours on first put down, wake for a feed but doesn’t want put down after his first nightfeed! For a while I was just co sleeping and we were fine with it but if I want to see my 30th birthday without being the shape of a quaver from back pain I need to stop this 🤣
