Dear May,

I can recommend you start reading the information that is available on the following website About skillsforaction.com | skillsforaction.com
On it my colleague gives a lot of information not only about normal developing infants, but also about infants that are having problems.
She has some very good ideas and suggestions with pictures and video's. Please take your time to read everything Pam writes on her site.

One practical suggestion to start helping your baby is, changing the supporting plane... if you give your child a diagonal plane he/she might be able to lift his/her head.If this is the case, let him/her practice this a lot.

kind regards

Esther
