3 month behaviour change

[Pinkfuzzyduck33]

My DS has just turned 3 months old. He has been a relatively chilled out baby, alert and quite happy going out and about and being with other people. he has also been a really good sleeper and stuck to the routine of waking at a similar time of night for a few weeks now.

in the last week his behaviour has changed, he has become more fussy, agitated if he’s not with me (mum) and walking more frequently in the night. He has also had a lot of change in the last week, we went away for the weekend, over a period of a few weeks I have been transitioning to formula feeding with this week being adding in another bottle rather than breast feeding.

this may all be completely normal but I am wondering where my chilled out, happy little boy has gone and concerned I’m doing something that is making him unhappy ! Is this a growth spurt ? Is it feeding ? Is it just one of those things now he’s hit 3 months ?

any tips/reassurance would be gratefully received.

It could just be normal baby behaviour and they do have a growth spurt at around 3 months.

When he wakes, does he go bank to sleep if you feed him?

Yes he feeds from me then goes back to sleep 😊

I think he's

a, going through a growth spurt,

and b, probably realised that you can be separated from one another. Just give him reassurance.

Now he's having a bottle, does DO/DH take him out on his own at all? If he's free at the weekends I'd encourage him to take DS to the park/library/swimming/shopping centre to get DS used to you not always being the main carer. It will also give them some time alone to bond.
